Mrs. deford wanted to know whether or not her students would do better on a quiz if she promised them candy. she went to the library and read several studies about the effect of giving food to lab animals. she found out that if animals were given food as a reward for doing something, they usually did better the more reward they were given. she figured that the more candy her students were promised, the better they would do on the quiz. she had all of her classes participate in the experiment; there were four groups in all. each group had the same number of boys and girls, they were all given the same quiz, they were all the same age, of the same ability, and they came from the same background. the first group was not promised any candy. the second group was promised 1 candy bar if they did well on the quiz. the third group was promised 2 candy bars and the fourth group was promised 3 candy bars, for doing well on the quiz. group #1 got an average of 70% on the quiz. group #2 got an average of 80%, group #3 got an average of 90%, and group #4 got an average of 95%. identify the following: a. independent variable: b. dependent variable: c. constants (at least 2): d. testable question: e. hypothesis: f. formal conclusion statement (refer back to the / the data :

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
